Description

Technical Field

[0001] This utility model relates to the field of potato starch processing technology, and in particular to an airflow drying device for potato starch processing. Background Technology

[0002] Against the backdrop of the booming global food industry, potatoes, as the world's fourth largest food crop, are experiencing continuous expansion in their processing industry. With consumers' increasing demand for high-quality food ingredients, potato starch, thanks to its excellent properties, is finding increasingly widespread applications in numerous fields such as food, papermaking, textiles, and pharmaceuticals, becoming one of the key raw materials supporting the development of these industries. According to relevant statistics, global potato starch production has steadily increased in recent years, which undoubtedly places higher demands on potato starch processing technology.

[0003] Potato starch drying technology basically follows the principle of heat transfer to promote moisture evaporation. Taking drying in a drying room as an example, hot air is introduced into the closed space. By utilizing the temperature difference between the hot air and the wet starch, heat is transferred from the hot air to the surface of the wet starch and then penetrates into the starch, causing the moisture in the starch to gradually evaporate.

[0004] In existing technologies, the common drying oven technology, although free from the constraints of weather to some extent, suffers from serious problems of low drying efficiency. The heat distribution inside the drying oven is uneven, and starch near the heat source is prone to scorching due to overheating, while drying is slow in areas far from the heat source, resulting in inconsistent product quality. To address these issues, an airflow drying device for potato starch processing is proposed. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1 to 3This utility model provides an embodiment of an airflow drying device for potato starch processing, including a hot air furnace 1. The hot air furnace 1 provides a continuous and stable heat source for drying potato starch, ensuring the smooth progress of the drying process. A conduit 11 is fixedly connected to the outside of the hot air furnace 1, which serves as a hot air transmission channel. A shell 7 is fixedly connected to the outside of the conduit 11. A uniform drying mechanism is provided inside the shell 7. A crushing component for placing agglomerates is fixedly connected inside the shell 7. The shell 7 is a mixing area for hot air and materials, ensuring that the drying process is concentrated and orderly. A drying pipe 12 is fixedly connected to the top of the shell 7. The drying pipe 12 provides the main site for mixing, heat transfer and mass transfer of hot air and starch. Hot air carries starch and flows rapidly in it. During this process, the starch fully absorbs the heat of the hot air, and the moisture evaporates rapidly to achieve the drying purpose. A separation component for filtration and separation is provided at the top of the drying pipe 12. A feeding mechanism is provided at the top of the hot air furnace 1.

[0025] The uniform drying mechanism includes a support column 18, which is externally fixedly connected to the inside of the outer casing 7. A protective shell 19 is also fixedly connected to the outside of the support column 18, supporting the protective shell 19. A braking assembly for adjustment is fixedly connected inside the protective shell 19. Guide vanes 20 are fixedly connected to the outside of the braking assembly. The braking assembly includes a motor 21. The protective shell 19 provides a safe and enclosed environment for the braking assembly, preventing dust, moisture, and other impurities from entering and affecting the normal operation of components such as the motor 21, thus extending its service life. The motor 21 is externally fixedly connected to the inside of the protective shell 19. A push bar 22 is fixedly connected to the drive end of 21. The motor 21 is used to push the push bar 22. A gear is provided on the outside of the guide vane 20. The gear on the outside of the guide vane 20 meshes with the rack on the inside of the push bar 22. The push bar 22 is used to reciprocate under the drive of the motor 21. Through the meshing of the rack and the gear on the outside of the guide vane 20, the power is effectively transmitted, driving the guide vane 20 to rotate flexibly. The guide vane 20 is used to guide the hot air to form a uniform and stable airflow at the inlet of the drying tube 12, so that the hot air and starch granules are fully and uniformly mixed, accelerating the drying process. The top of the outer shell 4 is fixedly connected to the feed port 5.

[0026] Reference Figure 1 , Figure 2 and Figure 4The feeding mechanism includes a housing 4, the bottom of which is fixedly connected to the top of the hot air furnace 1. Inside the housing 4, two spiral rods 23 are rotatably connected. The spiral rods 23 are used to rotate under the drive of the motor 2 to smoothly and uniformly push the material entering from the feed inlet 5 to the guide tube 11, ensuring a stable feed flow and preventing blockage. The housing 4 is used to support the motor 2. The motor 2 is fixedly connected to the outside of the housing 4. The drive end of the motor 2 is fixedly connected to one end of the spiral rod 23. The other spiral rod 23 is fixedly connected to the outside of the rotating column 3. The rotating column 3 and the drive point of the motor 2 are externally coupled by a belt. The belt outside the motor 2 drives the rotating column 3 and the spiral rod 23 to rotate together.

[0027] The crushing assembly includes a second motor 6, which is externally and fixedly connected to the inside of a second housing 7. A rotating shaft 8 is fixedly connected to the drive end of the second motor 6, driving the rotating shaft 8 to rotate. Multiple crushing plates 9 are fixedly connected to the outside of the rotating shaft 8, rotating under the drive of the second motor 6. A screen barrel 10 is slidably connected to the outside of the crushing plates 9, allowing them to rotate synchronously with the rotating shaft 8. The screen barrel 10, fixedly connected to the inside of the second housing 7, screens the crushed starch granules, allowing only starch that meets the particle size requirements to pass through, blocking large, insufficiently crushed particles, ensuring uniform particle size of the material entering the drying tube 12, and guaranteeing the drying effect. The separation assembly includes a second conduit 13, one end of which is fixedly connected to the drying tube 12. Outside the drying tube 12, the second conduit 13 is used to ensure that the dried material can be smoothly and quickly transported to the cyclone separator 16 for separation. A support frame 14 is slidably connected to the outside of the second conduit 13. The support frame 14 is used to stably support the second conduit 13. The bottom of the support frame 14 is fixedly connected to the top of the outer shell 4. The other end of the second conduit 13 is fixedly connected to the cyclone separator 16. A fan 15 is fixedly connected to the top of the cyclone separator 16. The cyclone separator 16 uses the principle of high-speed rotating airflow to make the air carry starch in a circle inside. The heavier starch particles are made to settle to the bottom by relying on centrifugal force, so as to separate the air from the starch. The fan 15 is used to move the airflow inside the cyclone separator 16. The bottom of the cyclone separator 16 is fixedly connected to the discharge port 17 for discharging the material.

[0028] Working principle: The material is fed into the outer shell 4 through the feed port 5. The motor 2 drives the belt outside the rotating column 3 to drive the two screw rods 23 to rotate together, pushing the material into the guide tube 11. At the same time, hot air is generated by the hot air furnace 1 and enters the outer shell 7 through the guide tube 11, blowing the clumped starch into the outer shell 7. At the same time, the motor 6 drives the rotating shaft 8 to rotate. The rotating shaft 8 and the crushing plate 9 rotate simultaneously to break up the clumped starch. After being crushed by the screen barrel 10, the crushed starch is blown into the drying tube 12.

[0029] The motor 21 inside the protective shell 19, supported by the support column 18, drives the push bar 22 to move, and the guide vane 20 rotates, making the mixing of hot air and starch more uniform. The dried material in the conduit 13 supported by the support frame 14 is then fed into the cyclone separator 16 by the fan 15. The cyclone separator 16 carries the starch in a circular motion and slowly falls to the bottom, where it is collected through the discharge port 17, and the dried starch is separated out.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
